Ouch indeed. The book disappeared off the sales chart in weeks 2 and 3 when position 10 was about 1k so you could posit sales of maybe 4k so far. I saw a review on amazon.co jp which might give a clue as to the sales, "this book is good for Chiba Erii fans but not for photobook collectors". If you don't do mizugi then you're automatically limiting the potential sales. She also didn't get any manga magazine covers which AKB centers would have used to get previously so promotion was lacking. Now I know Erii doesn't have a traditional grav body but then YuiYui doesn't either and some guys like the "gamine" look. Confession though...I'm kind of tempted to buy it though, Erii does have a really pretty face

Manager-san responses are more interesting. After the initial buzz the content and perhaps the subject is unfortunately bland. to up the views, elle (eri) either needs to 1) track down rei and kubo for a video, 2) cover kpop dance with satomina and nami, (asai yuka is still around but does anyone, even zest remember her?) 3) film her feet. I would suggest bikini snow dance but if elle loses a few more grams she will lit. freeze to death.
